System Preferences may unexpectedly quit in Mac OS X 10.4.8 after setting the iTunes Artwork screen saver to use two rows in Desktop & Screen Saver preferences. You may not be able to open System Preferences after this happens.
To avoid the issue, use any iTunes Artwork screen saver Row setting besides 2 (the default is 5).
To resolve the issue if you are affected, go to your Home folder and remove a plist file (~/Library/Preferences/ByHost/com.apple.screensaver.iTunesArtwork.xxxxxxxxxxx.plist) :
Note: Removing this file may reset other System Preferences settings. Adjust your System Preference settings as desired.
This document will be updated as more information becomes available.
